Never heard of that problem but like he said that's real easy to fix. Sit the machine on the ground with the box sitting flat and mounted as normal under the shaft. That will make it easier to adjust the coil mount by eye (with coil on) to see that it's straight in relation to the box/grip/arm cup. If you are using Gorilla Glue once the thing is line up then wrap the coil/mount in a little tape to hold it and also to keep the glue from escaping as it forms up. I use this glue a lot in building RC airplanes and it's great/light/strong stuff, but if you don't tape and weight things together the foaming glue can force things to move. I'd put a weight on the coil (laying flat) and also tape around the two parts tight. Also, DON'T use a lot of glue. Mix a TINY bit of water with the glue and just hardly paint it on the coil mount before sticking it inside the uper shaft. This stuff foams up about 10 to 20 times it's size and you'll force a bunch up the shaft if you use too much. I'd play with it by mixing a tiny bit of water with about two teaspoons of the glue and stick that in a cup so you can see just how much this stuff foams up. Another option is to just use CA or epoxy. By laying the coil flat on the ground along with the box and such you can more easily make sure all is lined up well.
